Some potentially useful options to consider?

1. I believe the plot option in appraise chooses a single marker that is representative of the metagenomes, assemblies, and bins. An option to identify this marker without plotting might be helpful.

2. In some cases, folks might be interested in clustering and summarising OTU tables for a particular marker, for example, the one identified above, so an option to summarise a particular marker may be helpful.
